Inspired by the antifouling properties of shark skin and the bioadhesion of mussels, our study presents a three-layer biomimetic wound dressing with hierarchical wettability and rapid exudate drainage capabilities. The shark skin-inspired hydrophobic modified polyurethane (PU) sponge provides antifouling properties and serves as a bacterial barrier. The mussel-inspired dopamine-functionalized carboxymethyl chitosan hydrogel (CMCS-DOP) absorbs exudates and forms an in situ hydrogel, effectively capturing and eliminating bacteria. The porous sponge layer in direct contact with the wound facilitates rapid exudate drainage, preventing excessive wound hydration. This hierarchical structure coordinates exudate transport and bacterial removal. The fabricated PCD hydrogel sponge dressing (PCD dressing) exhibits a wettability transition (contact angle: 3°–35°–101°) and a water vapor transmission rate of 1021–797–691 g/m². It demonstrates potent bactericidal effects against Staphylococcus aureus and Escherichia coli, with survival rates of only 13 % and 14 %, respectively, and bacterial-blocking efficiencies of 89 % and 94 %. In a chronic bacterial infection wound model, the PCD dressing outperforms conventional clinical dressings, increasing the wound healing rate by 25.8 %, reducing inflammation, and enhancing angiogenesis and collagen deposition. Notably, the PCD mitigates oxidative stress at the wound site by regulating the polarization of anti-inflammatory macrophages. This exudate-draining and responsive dressing offers a promising strategy for promoting the healing of wounds with high exudate levels.

Robust hydrogen evolution reaction (HER) electrocatalyst is of significance important for the realization of water splitting technology. In this work, we report the nitrogen doped carbon nanotubes confined CoRu alloy nanoparticles (CoRu@NCNT) as superior HER electrocatalyst. The d band center of Ru atom is downshifted resulting in loosening the hydrogen binding strength; therefore, a robust HER activity is achieved for CoRu@NCNT with mass activity enhanced by 6-time than commercial Pt/C and CoRu/NCNT in both acidic and alkaline mediums. Moreover, compared to CoRu/NCNT electrocatalyst, CoRu@NCNT exhibits a better HER performance attributed to the prevention of avoidable surface oxidation of Ru. Moreover, a more moderate Gibbs free energy for hydrogen is achieved for CoRu@NCNT. Similarly, the stability of CoRu@NCNT outperforms CoRu/NCNT stemming from the NCNT confinement effect suppressing the movement and coalescence of CoRu nanoparticles.

In this work, pre-magnetized ε-Fe₂O₃ was used as prototype electrode material to reveal the synergetic effect between ferromagnetism and electrochemical performance. Upon high-rate potassiation, ε-Fe₂O₃ was unable to fully participate in conversion reaction due to “potassiation retardation”. The higher the rate was, the less complete the conversion reaction became. The as-converted Fe product was magnetized by the remanent magnetization of residual ε-Fe₂O₃ and underwent a magnetic decantation process. As a result, the Fe phase was magnetically attached to the residual ε-Fe₂O₃ surface, while the diamagnetic K₂O phase was separated out. This phase separation not only suppressed the generation of KOH but also made side reactions involving − COOK species less likely to occur, thereby avoiding a large consumption of electrolyte and stabilizing the solid-electrolyte interphase layer. Driven by this synergy, ε-Fe₂O₃ showed the best cycling stability on potassium storage at 5 A g⁻¹. Its discharge capacity loss per cycle was as low as 0.094 ‰ from 4 to 700 cycles with Coulombic efficiencies above 99.9 %. Moreover, the results also showed that the rate influence on potassium storage was much greater than that on lithium storage. It was thus anticipated that this work would shed new light on the understanding of interrelated physicochemical properties of electrode material.

A general strategy to enhance surface hydrophobicity through modifying a rough-textured surface with weakly hydrophilic elemental sulfur

Lotus leaves usually get the superhydrophobicity from the presence of epicuticular wax on its multilevel micro- and nano-structured surface. It is known that the epicuticular wax is weakly hydrophilic with a contact angle of ∼ 74°, and inorganic elemental sulfur also has a weak hydrophilicity similar to the wax. Inspired by the waxy feature, here we first attempt a superhydrophobicity-harvested strategy by modifying a rough surface with weakly hydrophilic elemental sulfur. The superhydrophobicity of a series of materials including metal hydroxides, oxides, sulfides and chlorides, metals, and even hydrophilic organics, can be achieved by prefabricating their topographic textures combined with elemental sulfur surface modification. DFT calculation suggests that the presence of V_S defects on the elemental sulfur coatings can make their rough surfaces have a stronger affinity for O₂^2– than for H₂O, which allows for the formation of O₂^2–-adsorbed layer on their surface, and thus imbues the hydrophobicity or superhydrophobicity. Our study offers a new and general approach to enhance the surface hydrophobicity via inorganic rather than low surface-energy organic modification.

In-situ modulation of the synergistic effect of both radicals and non-radicals is crucial in the activation of peroxymonosulfate (PMS). In this study, we show a layer-structured carbon nitride with anchored cobalt single atoms was facilely synthesized (0.2Co-CN), followed by an investigation of the mechanism and performance in activating PMS for the removal of emerging contaminants (ECs) assisted by visible light. The results indicate that under visible-light excitation, the catalytic system achieved 97.1% degradation of Norfloxacin (NOR) within 60 min, representing a 3.3-fold increase in kinetics compared to conditions without light. Experimental characterization reveals that the anchored single-atom Cobalt is prone to adsorbing and concentrating PMS, thereby favoring the activation; This observation is further supported by density functional theory calculations. The degradation mechanism shifts from a pure radical pathway to a synergistic pathway involving both radical and non-radical, under in-situ light irradiation. This light-assisted modulation significantly increases both the variety and concentration of reactive oxygen species(ROS), leading to effectively enhanced catalytic performance. The catalyst exhibits robust functionality across a broad pH range without metal ion leaching, possesses unmoved interference resistance without compromising efficiency, demonstrates excellent reusability without significant fatigue, and shows applicability to various ECs and diverse real-world water bodies, paving the road to potential industrial level applications.

Redox-active graphene dispersant and its ability to improve the conductivity and pseudo-capacitance of carbon film

IF 9.4 1区化学 Q1 CHEMISTRY, PHYSICAL

Hypothesis

Strong van der Waals force and π–π interaction make graphene difficult to be uniformly distributed in basic matrix for fabricating graphene-based composites. Employing dispersant is a major solution, however, current existing dispersants such as commercially available surfactants and polymer stabilizers scarcely provide ideal effect. Besides, they are always “useless” in final composites but difficult to remove. Therefore, endowing dispersant with specific property that matching the application of the final composite is essential.

Experiments

Herein, a redox-active graphene dispersant (RAGD) is developed based on the grafting of p-phenylenediamine (PDA) with epoxy groups and further reacting with ethylamine. Homogeneous aqueous graphene dispersion is prepared by tip-sonication, and uniform graphene-based films are prepared via vacuum filtration method.

Findings

Graphene can be homogenously dispersed in water with concentration up to 15 mg mL⁻¹ in the presence of RAGD, and it can stably exist at room temperature for over six months. The π–π interaction of RAGD with graphene is tunable due to the PDA conjugated center is redox-active, and RAGD can be partially eliminated from graphene under alkali treatment. The electrical conductivity of the graphene film increases by about 34% after treated by 1 mol L⁻¹ NH₃·H₂O. Additionally, the graphene-based film including RAGD also shows much higher specific charge capacitance than those made with commonly used surfactants.

The surging demand for lithium in energy storage necessitates sustainable and efficient electrochemical lithium recovery from salt lakes. Herein, we develop Ni-doped LiMn₂O₄ microsheets (LNMO-MS) via a green bio-templated synthesis that integrates 2D morphology engineering and Ni-doping using chitosan biopolymer as a structural guide. This dual modulation addresses intrinsic limitations of conventional LiMn₂O₄. Ni doping induces [MnO₆] octahedral contraction to stabilize the framework and enhance Li⁺ selectivity (Mg²⁺/Li⁺ separation factor: 401.32 at Mg²⁺/Li⁺ = 200), while the 2D architecture shortens Li⁺ diffusion paths, enabling 10-fold faster ion kinetics and improved charge transfer. In capacitive deionization (CDI), the LNMO-MS achieves a record Li⁺ adsorption capacity (4.12 mmol g⁻¹), with low energy consumption (1.96 Wh moL⁻¹ Li⁺), outperforming conventional LiMn₂O₄ electrodes. Real-world validation using Qarhan Salt Lake brine demonstrates practical viability, producing concentrated LiCl solutions (1 g L⁻¹ Li, Mg²⁺/Li⁺=0.13) at 8.63 Wh·mol⁻¹ Li⁺, while maintaining 92 % capacity retention over 200 cycles. The strategy of bio-guided 2D structuring and Ni doping establishes an energy-efficient, durable platform for selective lithium extraction, offering a sustainable solution to bridge lithium supply–demand gaps with minimized environmental footprint.

The global freshwater crisis poses a substantial threat to sustainable development, driving urgent demand for advanced atmospheric water harvesting technologies. While bio-inspired fog collectors have shown potential, conventional single-scale architectures often exhibit suboptimal performance due to inadequate coordination between droplet nucleation and transport. Here we present a multi-object-coupled venation-shaped patterned surface (MVSS) fabricated through laser-etching of filter paper/polydimethylsiloxane composite films. By synergistically integrating three bio-inspired mechanisms: (i) heterogeneous wettability patterns mimicking desert beetle elytra, (ii) conical spine arrays inspired by Opuntia histophysiology, and (iii) hierarchical venation networks derived from plant leaf, we establish a multi-stage phase-transition process that enhances fog harvesting efficiency through coordinated surface energy gradients and Laplace pressure modulation. The wettability contrast enables selective droplet nucleation, while the conical geometry generates asymmetric contact line pinning that drives directional transport. The hierarchical branching network minimizes hydraulic resistance through optimized flow path partitioning, achieving rapid drainage while suppressing edge water accumulation. This multi-scale synergy yields a record water collection rate of 1033 ± 28.2 mg cm⁻² h⁻¹. Our findings elucidate the critical role of structure–property coordination in fog water collection, providing a generalized design paradigm for developing high-efficiency atmospheric water harvesters. The fabrication strategy combining scalable laser processing with bio-composite materials suggests promising pathways for arid region deployment.

Hypothesis: Aqueous nanobubble solutions (NBs) have demonstrated a remarkable ability to displace hydrophobic fluids (e.g. oil) from porous media compared to blank water, although the underlying mechanisms remain unclear. Through detailed characterization of fluid behavior within porous spaces under controlled conditions, microfluidics can help uncover the fundamental origins of the NB-induced effects.

Experiments: We systematically evaluate the impact of NBs on two-phase flow dynamics within porous media by applying glass micromodels that mimic both extreme wettability conditions: strongly hydrophilic (water-wet “WW”) and strongly hydrophobic (oil-wet “OW”). An innovative system that combines membrane dispersion technique with microfluidic flow was used to generate NBs at elevated pressures for flooding tests.

Findings: In OW scenarios, NBs demonstrated superior sweep efficiency compared to distilled water, achieving more uniform front propagation and reducing bypassed oil volumes. The improvement can be attributed to the interfacial activity of NBs along with their specific interactions with solid surfaces. In particular, NBs lowered the interfacial tension (IFT) between the oil and aqueous phases, leading to weaker capillary forces that aid in effective oil mobilization. At the pore walls, NBs induced a slippage effect that reduced the pressure drop across OW media, further facilitating displacement. Aside from these fundamental insights, our results demonstrate the utility of N₂ NBs for oil recovery and related applications at elevated pressures, which are often encountered in practical settings.

Retired Lithium-ion batteries (LIBs) present significant challenges related to environmental pollution, making the recycling of battery materials essential for environmental sustainability and energy recovery. Cobalt has been identified as an effective catalyst for oxidation reactions; accordingly, Co₃O₄ was recovered from batteries directly for use in preferential CO oxidation (CO-PROX). To enhance the low-temperature catalytic activity, supported CuO/Co₃O₄ catalysts were synthesized, resulting in a remarkable boost in catalytic performance, with thorough CO conversion (T_100%) at 160 °C. However, the way a reaction occurs remains unclear, and the active sites for CO adsorption require further investigation. Characterization techniques and density functional theory (DFT) calculations indicated that CuO/Co₃O₄ exhibits higher lattice oxygen (O_latt) content and strong metal-support interactions, which facilitate CO adsorption while suppressing hydrogen activation. Moreover, in-situ diffuse reflectance infrared Fourier transform spectroscopy (in-situ DRIFTS) analysis was used to analyze reaction intermediates, verifying that CuO/Co₃O₄ significantly enhances both CO conversion and CO₂ selectivity. This research presents a viable strategy for the recycling of retired LIBs and the advancement of efficient catalysts for CO-PROX.
